6 Claims.

Tlf'ijepresent' invention consists of a copyholder embodyingimprovements over my former Patents No'. 1,939,671,13eeember I9-, 1933a|nd No. 2,162,706, June 2U, 1939. l

Infthe present' invention I' providenovel drive means for the feedrol-1erv effecting more delicate spacing of the copy, yet retaining-thedesirable spacerf bar and; adjusting means;

I 'haver found that .itA is desirable at times; to need; copy more: or:`less than. a. certain number of? set; spacestetwliichy my previous`machines arellimited. It; is consequently the desideratum of the:present. invention to` provide a copyholder wherein the copy may be fedto any extent de-` sirediby the operator down to the smallest fractionof an inch, thereby permitting universal spacing.

The means employed in the present invention for effecting universalspacing has been found, after much experiment, to be extremely accurateand sensitive and is capable of facile adjustment to change the degreeof spacing at the option of the operator.

Other objects of the invention will be apparent from the followingdescription of the invention, taken in connection with the accompanyingdrawing, wherein Fig. l is a perspective View of a copyholder',

Fig. 2 is a vertical sectional View showing to advantage the feed rollerdrive means of the present invention, the latter being shown in sideelevation,

Fig. 3 is a detail fragmentary sectional View taken on the line 3-3 ofFig. 2, and showing to advantage the improved axle of the presentinvention and manner of mounting the same,

Fig. 4 is a detail fragmentary sectional View taken on the line 4 4 ofFig. 3 showing the mannerof mounting one end of the axle in one of thecasing ends,

Fig. 5 is a perspective view of the axle per se, and

Fig. 6 is across sectional view taken on the` latter, is an axle I0, theends of which are attfened, as indicated at II, andmounted incomplemental slots I2, formed in plates I3, the latter being mounted intheV ends or the sides of the casing.` A feed roller I4- issleeved overtheY axle Ill and is spaced from the latter by an annulus I5. Theannulus is formed on the axle approximately midway itsends, asillustrated to advantage in Fig. 3. To preventA tilting of the endsv ofthe roller onv the axle ISI, I equip the latter with protuberances I6,one of the latter being formed adjacent each terminal of the axle.

IPaper `feed-ringsv IIT are mounted on the roller I4,

portions of' the peripheries thereof being projected through`compl'emental slots formed in the front wall of! the casing andvemployed in a man.- ner well known in the art.

The feed roller I4 is formed to provide spaced annular rings I8, havingtherebetween a runway over which a belt I9 is trained. Both ends of thebelt are anchored to hold the intermediate portion thereof in frictionalengagement with the periphery of the roller in the runway between therings I8, the latter, of course, preventing lateral displacement of thebelt.

For the purpose of operating the belt I9, I employ a spacer bar 2l!which is similar in construction to that shown in my Patent No.2,162,706, and is adapted to be operated in the same manner. The spacerbar, however, in the present invention, forms a part of the compoundlevers 2| and 22, these levers being hingedly connected, as indicated at23. The inner end of the lever 2l is hingedly connected, as indicated at24, to the casing 1, at the juncture of the rear and bottom walls of thecasing. The terminal of the lever 22 is engaged with the floor of thecasing at the front of the latter, while the rear terminal is engagedwith one end of the belt I9. The opposite end of said belt is secured toone end of a coil spring 25, the opposite end of said spring beinganchored, as indicated at 26, to the upper face of the lever 22, atapoint remote from the terminals of the latter. By this arrangementpressure on the spacer bar 20 urges the inner or rear end of the lever22 downwardly to drive the feed roller I4.' As soon as pressure isreleased' on the spacer bar 20, the latter is returned to an operativeposition through recoil of the spring 25.

In order that the extent of movement of the roller I4 may be adjusted, Iemploy suitable means, such for instance, as a cam 21. The cam ismounted to ride on the lever 22, under operation of a handle grip 28.There is interposed between the periphery of the cam 21 and lever 22,asound dampener or deadener 29, to eliminate the noise'incident to impactof the lever with the cam upon return of the spacer bar to a normaloperating position.

In using the invention, after the copy has been placed in the holder, itmay be moved by rotation of the paper feed rings l1. The feed rings are,oi' course, rotated through action of the roller drive means, the latterin the present instance consisting of the belt I9 and its associatedmechanism, including the spacer bar 20. By this construction theoperator is not limited to any predetermined spaces Which must ofnecessity be employed. He can optionally select any space within thelimits of operation of the machine.

It is, of course, to be understood that various changes may be made inthe details of construction, proportion and arrangement of parts, withinthe scope of the claims hereto appended.

What is claimed is:

l. A copyholder comprising a casing equipped with an axle and a paperfeed roller sleeved thereover, the latter being spaced from the axle androtatable on the latter, and means mounted on the axle to preventrelative radial movement of the roller on the axle.

2. A copyholder comprising a casing equipped with an axle, the terminalsof the latter being flattened, plates mounted on opposite Walls of saidcasing and provided with slots complementing the flattened portions ofsaid axle, the terminals of the axle projected through said slots intoengagement with the casing Walls, and a paper feed roller rotatablymounted on said axle.

3. A copyholder comprising paper feed mechanism movable about a xedaxis, drive means for the mechanism, and manual operating meansconnected to the drive means and operable to effect movement of thelatter, the drive means including a slip belt and compound levers forpositively actuating the mechanism any degree, predetermined by theoperator, Within the range of movement of the mechanism.

4. A copyholder comprising a copy feed roller, a hand operating slipbelt trained over the roller, and means in operative connection with thebelt to move the latter to a fixed predetermined degree for eiecting acorresponding degree of movement of the feed roller, said meansincluding compound levers one of which levers is engaged with said beltand the other anchored beneath the roller.

5. A copyholder comprising a paper feed roller rotatable about a fixedaxis, and drive means for the roller` operable to move the roller to anypredetermined xed degree Within the limits of movement of the rolleroperating mechanism, said means including coacting levers and a slipbelt, an intermediate part of the latter engaging the roller, one end ofthe belt being engaged With one of said levers.

6. A copyholder comprising a copy feed roller, a manually operable drivebelt trained over the roller, means in operative connection with thebelt to move the latter longitudinally around the periphery of theroller to effect movement of the latter, said means including leversengaged with the belt.
